I have a SCSI controller board (501-1045 Rev 5) that once was used with a
501-1059 Multibus-to-VME adapter in a system with internal SCSI tape and
disk.  I'd now like to put the SCSI board on a Helios memory board
(900-12S-A) and use the external SCSI connector on the Helios board.  This
will be in a 3/160 deskside enclosure with a 3/160 (501-1208 Rev 13) CPU.

As currently configured, this doesn't work.  The system fails to boot,
complaining about various bus errors.  Does anyone have the information I
need to reconfigure the SCSI board and/or Helios memory board?  Even the
information that this mating is impossible would be of help.
